Summary of the invention
Problem to be solved by this invention is how to make two sections of spud legs carry out centering welding.In order to realize the continued access between spud leg, manufacture and utilize positioner, by the location of positioner, realize the wielding neck of upper and lower two ends spud leg, form spud leg connector.For this reason, case type spud leg assembling and positioning device and method has been proposed.Utilize this positioner and method, solve the technical problem that two sections of spud legs align connection.
The scheme that technical solution problem of the present invention adopts is:
Positioning device structure:
Spud leg buttcover plate is two plate objects that overlap up and down, is provided with butt hole and pin shaft hole on every plate object, forms positioner;
At the upper spud leg that is provided with reinforcing rib, be connected respectively spud leg buttcover plate with on lower dress leg, the butt hole of two spud leg buttcover plates is fixed with bolt, and pin shaft hole grafting bearing pin, positions;
Alignment device is provided with two to multipair in spud leg surrounding.
Utilize positioner to connect the method for spud leg:
1) the upper spud leg first needs being closed up and lower spud leg be centering location on flat-tyre, is symmetrically welded spud leg contraposition body, forms positioner;
2) upper spud leg and lower spud leg positioner are synthesized to one with bolt by butt hole handle;
3) then use bearing pin is inserted in pin shaft hole, locate upper and lower positioner;
4) positioner interval is uniformly distributed and is welded on spud leg cylindrical shell surrounding and closes up Kou Chu;
5) positioner and the welding of upper spud leg;
6) positioner and the welding of lower spud leg;
7) pull and close up after mouthful inspection line, positioner connects to be removed, upper spud leg installation;
8) when lower spud leg is installed, utilize positioner location, utilize and check line check, complete lower spud leg and install;
9) upper spud leg and the welding of lower spud leg folding, complete the connection of two sections of spud legs.
Good effect, the frock that spud leg proposed by the invention is located by connecting is applied in the continued access of spud leg and locates above, can guarantee that spud leg contraposition is accurate, prevents flexural deformation, can improve spud leg installation rate simultaneously.Suitablely as shipyard machine tool field spud leg assembling and positioning device and method, apply.
Accompanying drawing explanation

Fig. 3 is spud leg docking side sectional view of the present invention
In figure, 1. spud leg, the upper spud leg of 1.1., spud leg under 1.2., 2. spud leg buttcover plate, 3.1. pin shaft hole, 3.2. butt hole, 4. reinforcing rib.
The specific embodiment
Positioning device structure:
Spud leg buttcover plate 2 is two plate objects that overlap up and down, is provided with butt hole 3.2 and pin shaft hole 3.1 on every plate object, forms positioner;
At the upper spud leg 1.1 that is provided with reinforcing rib 4, be connected respectively spud leg buttcover plate with on lower dress leg 1.2, the butt hole of two spud leg buttcover plates is fixed with bolt, and pin shaft hole grafting bearing pin, positions;
Alignment device is provided with two to multipair in spud leg 1 surrounding.
Utilize positioner to connect the method for spud leg:
1) the upper spud leg first needs being closed up and lower spud leg be centering location on flat-tyre, is symmetrically welded spud leg contraposition body, forms positioner;
2) upper spud leg and lower spud leg positioner are synthesized to one with bolt by butt hole handle;
3) then use bearing pin is inserted in pin shaft hole, locate upper and lower positioner;
4) positioner interval is uniformly distributed and is welded on spud leg cylindrical shell surrounding and closes up Kou Chu;
5) positioner and the welding of upper spud leg;
6) positioner and the welding of lower spud leg;
7) pull and close up after mouthful inspection line, positioner connects to be removed, upper spud leg installation;
8) when lower spud leg is installed, utilize positioner location, utilize and check line check, complete lower spud leg and install;
